Google for ASCII art editor or something like this... More on stackoverflow.com

This one's better in some regard: http://www.text-image.com/convert/ascii.html It automatically corrects the aspect ratio. The post's service does not consider that the monospace characters (with line height included) are higher than their width, so additional work is required on the side of the submitter. Ironically, the link I wrote above does not allow to grab images right from the Web. Another thing that makes this service better: You can opt for additional contrast, just in case the background of the image wasn't completely white. ... Hm, I see that in Reddit's comment display, the result is still too high. :P ` .+/:-.` `/yyyyo. yNosyyyysohm/..-ym- :N+ ``.-/Ms -No `dh` omo:-/dd. oN- -+sso:` ````-Ny``` `.-/osyyyyyhdhyyysso/-.` ./oss+-./syhyo/:-.``` ```.-:/oyhyo:.-+oso+-` `sms/-/hNdy/.` `-/ydNd/::sdy` +M- `:hd/` ./dh: .Ns oN.`sN/` .://:` `-//:. `+No``my .hdyN: `ooooo+ /ooooo. :Nyhd. ``` ``` ` `+Mo `ooooo+ /ooooo. sN+` +dmms` `sdmdo` `-ohhhs:` -M+ `-::-` .::-` +N. `MMMMM+ /MMMMM- `yMmo+odMd` `dh` `dd` `MMMMMo +MMMMM- /Mm. dMo -shhs. -Ns` `yN- `MMMMMo +MMMMM- -NN+` :NM/ dMMMMy -dd: omo:. `:omy /md. `MMMMMo +MMMMM- -dMNmNMd/ `mMMMMh /dd+. ./shddddddhs+. .omd/ `MMMMMo +MMMMM- `-::. `mMMMMh -odds/. `-/sddo- .+o+. ./os+. -/+osoo+:` -/ooso+/- `MMMMMo `:/ooso+/. +MMMMM- -/:` `/++NMMMMd++:` .omNddhso++////++oshddNmo` -NMMMN.:dNMMMMN: `/hNMMMMMMMMMNdo. `/hNMMMMMMMMMms:MMMMMo `+dNMMMMMMMMMmooMMMMM- sMMMh .NMMMMMMMMMMMMd` -hdNd``.-:/++++++/:-.``mNdh- :MMMMMdMMMMMMMm- /mMMMMMMMNNMMMMMMNy. /mMMMMMMMNNMMMMMNMMMMMo `oNMMMMMMMNNMMMMMMMMMMM- hMMMN `yMMMMMMMMMMMNs +No.my hd`oN+ :MMMMMMMMmhs+:` `yMMMMNy/.````-odMMMMN/ sNMMMMmo-````-omMMMMMMMo `hMMMMMd+-```.:sNMMMMMMM- hMMMN `..mMMMMh..` -No `Ns ym` oN: :MMMMMMm/` `hMMMMh- `oNMMMN: sMMMMMs` `sMMMMMMo `hMMMMN+` .hMMMMMM- hMMMN `mMMMMh yN` `Ns ym` `Ny :MMMMMd. oMMMMm` oMMMMm. :MMMMMs oMMMMMo oMMMMM/ `hMMMMM- hMMMN `mMMMMh yN `my hd Ny :MMMMM/ `NMMMMo.``````````...MMMMM+ hMMMMN` `mMMMMo NMMMMd -MMMMM- hMMMN `mMMMMh +M- hd `my -M+ :MMMMM- :MMMMMNmmmmmmmmmmmmmmMMMMMy NMMMMy yMMMMo .MMMMM+ mMMMM- hMMMN `mMMMMh `hd- oN. -N+ -dh` :MMMMM- /MMMMMMMMMMMMMMMMMMMMMMMMN+ MMMMMy yMMMMo -MMMMM+ mMMMM- hMMMN `mMMMMh `smo/Mo sM:oms` :MMMMM- -MMMMMs::::::::::::::::::. dMMMMm mMMMMo `MMMMMs .MMMMM- hMMMN `mMMMMh -shNN. .Nmhs- :MMMMM- dMMMMh +MMMMM/ /MMMMMo yMMMMN. sMMMMM- hMMMN `mMMMMh `-my` `hm-` :MMMMM- :NMMMMs` .+yy: `dMMMMm: /NMMMMMo -mMMMMd. `oNMMMMM- hMMMN `mMMMMh .:+odMo `sMho+:. :MMMMM- /NMMMMmo-.` `.-+ymMMMm` .dMMMMNs-.` `.:yNMMMMMMo :mMMMMmo-` `./hMMMMMMM- hMMMN `mMMMMh `sds+::+ms` .ym+::+yds` :MMMMM- -hNMMMMNmdhhhdmNMMMMMm+ .sNMMMMNmdhhdmMMMMMMMMMo -hNMMMMNddhddNMMMMMMMMM- hMMMN `mMMMMh sN/`````:dd/.````.+md:````./Ns -MMMMM. `:ymMMMMMMMMMMMMNmy/. -smNMMMMMMMMMMmsNMMMM+ `:ymMMMMMMMMMMNdyMMMMN. yMMMd dMMMMy odyyyyyyyhmdhyyyyhddhyyyyyyyd+ /hdh+ .:+shhdddhyo/-` `-+shhddhyo/. :ydh+` .:+shdddhyo:``+hdh/ .+so. -ydhs. ```````````````````````````` More on reddit.com

This is a pretty late response (and maybe not exactly what you're going for) but I put an image-to-text conversion app up on itch yesterday you could try. https://zebbeni.itch.io/ansizalizer . It outputs images in ANSI code so I don't know if it matches your requirements, but it does let you set your target character width/height ratio and output image size (in characters). It's a stand-alone native app written in golang so you might have to plunder some of the code in the git repo if you just want to write a simple cli. More on reddit.com
